Oldest gear still for sale is . . .


Some gear seem to last, others, not so much. 

Can anyone think of anything hifi thats been in production longer than the Denon DL-103 cartridge? 55 years and still plugging away! Kennedy was in the White House when he DL-103 first came out-

I use some McIntosh MC 60s made in 1960, makes them 57 years. Use them every day. Terry Dewick is my friend.

The original Quad ESL was an early one (1957), but went out of production for years, then back in. I believe it is again out of production. How 'bout the Klipschorn? What I find interesting is the once-dismissed but now back in fashion designs---the Thorens 124 and Garrard 301.
